trolling Means for the Valve of a Water- Supply Pipe, of which the following is a specification.

This invention. relates to a controlling me ns for the valve of a water supplypipe;

and the principal object of the invention is to provide a device for controlling the closing of the valve, and thus preventing the valve from moving to a closed position too rapidly. In supply pipes of this-character.

through the :(llHCllfllTQ-G pipe 114.

it has been found that valves which are now in use will, after being used for a certain lengthof time, close too rapidly and shut off the flow of water through the discharge pipe before desired. This attachment will cause the valve to close slowly and thus prevent the valve from being closed until a sutlicient amount of water has passed through the discharge pipe. Y

This invention is illustrated in the accompanving drawings wherein-- Figure 1 is a view showing thesupply pipe and easing of-the attachment in section, the movable elements of the attachment and the lower portion of the discharge pipe being shown in elevation; Fig. 2 an en-- larged sectional, view of the lower portion of the casing which forms a part of this attachment; Fig. 3 is an enlarged sectional view of the lower end portion of the stem which forms part of this attachment; Fig. 4 is a sectional view taken along the line 6-6 of Fig. 3.

In the accompanying drawings the numeral 10 indicates the supply pipe which communicates with the .valve housing 11 positioned above the discharge pipe 12 and.

divided from the discharge'pipe by means of the perforated partition 13 which forms a valve seat. The valve 14 which is intended to rest upon the valve seat 13 is carried. by the stem 15 which has its u per end threaded as shown in Fig. 1. through the center of the supporting bracket 16 and carries a nut 17 which securelv holds the hrac zet upon the stem. A clamping nut 18 placed beneath the valve 14 so that the bracket 16 and valve 14 will be held rigidly upon the upper end portion clan of the stem 15. The diaphragm 3L9 winch is This stem passes 7 carried by the bracket 16 is provided with openings 20 which permit water to pass through the diaphragm and thuspermit the diaphragm to move easily in the valve hous mg 11. r

A rocker shaft 21 is rotatably mounted in a shoulder or hearing 22 extending from the discharge pipe 12 and has its outer end portion bent to form a handle 23 by means of whichthe rocker shaft may be oscillated. This rockershaft may be connected with the stem 15 in any suitable manner so that when the handle '23 is raised, the valve "stem 15.

will be moved upwardly to movethe valye 14: olf'of the valve seat 13 and thus permit 7a,ter -..to flow from the supply? pipe 10 The attachment by means "of which the closing of the above dcscribedvalve is controlled will now be described. A casing which is provided with'a partition 27 is .connected with the supply pipe 10 by means of the clamping arms 28=which inclose the supply pipe and are connected-by ascrew bolt 2-9. These clamping arms .28 are'carriedby the cap 30 of casing 26 and it will thus be seen that the casing will be suspended beneath the supply pipe. A small pipe 31 has its upper and lower necks 32 and 33 combottom of the casing and adjacent the partition 9.7 so that the oil which is placed in the casing maypass from one end of the casing to the other. A needle valve 34 is provided so that the passage of the oil through the conduit or pipe 31 may be regulated.

' municating with the'casing 26 adjacent the p A lever, 35 is pivotally connected with i the supporting arm 36 and extends into the upper chamber 37 of the casing 26 through the slot 38. The inner end of'the lever 35 is pivotally connected with the upper end of the piston 39 so that by moving the outer end ot'the lever downwardly, the piston may. be drawn toward the top of the chamber .40

in which the oil is placed. A link 41 connects the lever with. arm 49 which arm is secured to the rocker shaft 21. It will thus be seen that when the handle is raised to oscillate the rocker sliatt, the lever 35 will be moved to draw the piston 39 upwardly.

The "lower end of piston 39 is provided with'threaded sections 43 and 14: so-thatclamping nuts and 46 may be placed upon. a

the piston 39. Upon the unthreaded section 47 of the piston between the threaded sections 43 and 44 there are placed the Washers point above the nut 45. The P 48 and 49 between which is placed the cup 50 formed of rubber, leather, or any other suitable material. A passage Way 51 is formed in thelloiver end portion of the piston and extends from the lower end to a which comprises the passage of oil passage 51has its supporting J slidably mounted in an opening formed in the yoke 54 extending transversely across the passage 51. It will thus be seen that as the piston moves upwardly, the oil may pass through the passage '51 as well as being forced through the pipe 31, whereas when the piston is moving downwardly, the pres sure of the oil will force the valve 52 against the lower end of the piston thus closing the passage 51- and'causing the oil to be forced slowly through the conduit 31. Therefore the piston 39 can be quickly raised but will b retarded in its downward movement thus preventing the valve 14 from seating upon the valve seat 13 before desired.

. The operation of this device is as follows: lVhen the handle 23 is raised, the rocker shaft 21 is rocked to raise the valve stem 15 and move the valve 14; oil of the valve seat 13. At the same time the lever is moved to raise the piston 39 to the upper end of the chamber in which the oil is placed, The weight of diaphragm, together with the suction caused by Water passing from the sup ply pipe 10 through pipe 12 will cause the valve 14 to return to the valve seat 13, The rapid closure of this valve 14: will, however, be prevented since when the valve 14 is closing, the lever maymove and this, movement is retarded by the fact that the piston head can only move slowly in the chamber 40. It will thus be seen. that a chamber has been provided which will regulate the closing of valve 14 and prevent the valve from aeoaose closing too rapidly. It will also be noted that by means of the needle valve 34, the passage of the oil through the conduit 31 is regulated and therefore by adjusting this closed and that after the attachment has been installed for some time so that the valve 14: seats more rapidly than desired, thencedle valve can be moved tomore completely close he neck 83 and thus cause the oil to pass more slowly through the conduit 31.

What is claimed is:

An attachment of the character described comprising a casing provided with a passage way leading from one end of the casing to the other end thereof, a piston head slidahly mounted in said casing between the terminals of said passageway, a piston rod extendinto said casing and carrying said piston head and having its inner end portion provided with a passageway leading from the lower end of the piston rod and terminating above the piston head in a side opening, a bridge extending across the inner end of the passageway in said piston rod and provided with an opening, a valve positioned beneath said piston rod, and a stem extending from said valve through the opensaid bridge, to slidably suspend the wreath the piston rod.
